Abstract
The present disclosure relates to a dispersed metal nanoparticle synthesis method and metal nanoparticles prepared thereby. Specifically, the present disclosure relates to a method of effectively preparing a dispersed metal nanoparticle using Taylor vortex flow even when using a small amount of stabilizer or using no stabilizer, and well-dispersed nanoparticles obtained thereby.
Claims6
A method comprising:
- preparing a dispersed metal nanoparticle by reacting a metal precursor in aqueous solution and under a Taylor vortex flow formed in a continuous Couette-Taylor reactor;
- and
- controlling at least one of a rotation speed of the continuous Couette-Taylor reactor above a critical speed, a mean residence time of the nanoparticles in the continuous Couette-Taylor reactor, and a feed concentration of the metal precursor to control dispersion of nanoparticles,
- and wherein the nanoparticles are copper-palladium alloy nanoparticles, the size of the nanoparticles is 0.5 to 10 nm, and the mean residence time is 2 minutes to 8 minutes.
